WALTER DUKE SMITHEY, QF BAY CITY, TEXAS.

Application filed August 22, 1917.

To all whom it may concern:

Be it known that I, l VALTER D. SMrrHEY, a citizen ofthe United Statesof America, residing at Bay City, in the county of Ma tagorda and Stateof Texas, have invented certain new and useful Improvements inTurbine-Motors, of which the following is a specification.

This invention relates to turbine motors, and means for controllingsame.

The object of the invention is to provide a simple and economical motorwhich'can be efiectively operated by motive fluid.

A further object of the invention is to provide'improved means forgoverning the speed of the turbine motor.

The invention also comprehends improvements in the details ofconstruction and arrangement of parts which will be hereinafterdescribed, and particularly pointed out in the claims.

In the drawings:

Figure 1 is a perspective view of my improved motor,

Fig.2 is a central vertical section,

Fig. 3 is'a detail view of the resilient duct,

. Fig. 4: is a transverse section of the motor.

1 indicates a motor casing formed with an inlet port 2, and an outletport 3 the latter communicating with a muffler 3 Between the inlet port2 and outlet port 3, is bolted at 4, a resilient element having an inletduct 5, which is formed'at its exit end with a V concave shield 6.Secured to a driving shaft 7, within. the casing 1 is a rotor 8, formedon its periphery with a plurality of pockets 9. The shield 6 snugly fitsthe periphery of the rotor and forms a tight joint to prevent the motivefiuid leaking from the pockets.

The rotor travels in oil contained in the casing, and the bottom of thelatter is formed by a detachable plate 11, which inclines downwardlytoward the rotor to form a well directly under the latter.

The casing 1 is provided with a hollow extension 12, which communicateswith'the inlet port 2. 13 indicates a valve seat formed in the extension12, to one side of the inlet port 2, and cooperating with this seat is avalve 14, the stem 15 of which extends up through the top of theextension, and is providedwith an adjustable nut 16.

The driving shaft 7, extends through an opening 17, in one side of thecasing 1, and which communicates with a chamber 18,

formed by an auxiliary casing 19, bolted or otherwise fastened to oneside of said casing. Bolted to the auxiliary casing 19, is a cap plate20, in which is formed a central bearing 21, for one end of the drivingshaft 7, and between the end of the latter and the cap plate isinterposed a strong cup shapethrust spring 22. This thrust spring forcesthe shaft 7 laterally which retains a flanged washer 23, snugly againstthe bearing 24, in the opposite side of the casing.v

The auxiliary casing contains oil to lubricate the parts to bedescribed, and the thrust spring and washer serve as'a means forpreventing the oil leaking around the bearing.

Slidably mounted on the shaft 7 by a key and slot connection 25, is acone 26, located in the opening 17, and provided with cars 27, to whichlinks 28 are pivoted. The 0pposite ends of the links are pivoted toweights 29, which in turn are pivoted to ears 30, on a collar 31, fixedto the shaft 7.

32, indicates a vertical slidable lever mounted in a guidein the casing1, and pivoted at its upper end to a controlling lever 33, formed withan opening 34:, in which loosely fits the nut 16 on the valve stem 15.Pivoted to a standard on the extension of the casing is a handle 35, thefoot end 36.

thereof. engaging under the free end of the controlling lever 33, asshown. A spring 36", is attached to the controlling lever 33 A. coupling41-1, is screwed to the outer end of the extension of the casing, and inthis coupling is mounted a pressure regulating valve.

In operation the handle 35, is released, which causes the spring 36, toopen the valve 14, and the motive fluid passes through the inlet port 2,inlet duct 5, to the pockets on the periphery of the rotor. The shield6, acts as a packing, consequently the full effective force of themotive fluid acts on the pockets to rotate the rotor.

As the rotor travels at a rapid rate in a bath of oil, it follows thatthe bearings, be tween the shieldand the peripheral surface of therotor, and the shaft bearings will be thoroughly lubricated.

; As helsp edi flthe rotor increase b yo d 1 that set by thetension ofthe spring 36, the

weights 28, are centrifugally' thrown out- 7 wardly which slides.thelcone 25, on theshait 7, and elevates the vertical lever 32, whichraises the controlling lever 33 against the. tension of the spring 36,and correspond ingl-y raises-the valve El i, to itsseat' l3, and

shuts off thesupply of motive fluid. lmmee diately thespeed-of therotordecreases, the spring 36, acts to restore the lever valve, andtheweights act to restore thecone. 5
